Ionic bond (electrovalent bond) is the exchange of ions between atoms of different element while covalent bond is the sharing electron between atoms
To be at equilibrium means the rate of the forward reaction must equal the rate of the reverse reaction. This does not mean that there should be an equal amount of both products and reactants when at equilibrium. It simply means the RATES of the forward and the reverse are equal to one another.
Answer:
The question is incomplete, no worries I got you.
Here is the complete question;
__________ reactions are used to detect antibodies for relatively large pathogens, such as bacteria. For these tests, the antigen is mixed with the test sample at various dilutions. Reaction mixes are then monitored for the formation of visible aggregates.
Explanation:
AGGLUTINATION is the reaction used.
Agglutination is the reaction in which there is the clumping of particles. A agglutination reaction is the visible clumping of the bacterial cells as an antigen reacts with its corresponding antibody. This type is often used as an initial confirmation of specific pathogens. Agglutination tests is is used to detect antibody or antigen and it involves the agglutination of bacteria, red cells, or antigen- or antibody-coated latex particles. It is therefor used for large pathogens like bacteria. In this reaction, antigens are introduced into various dilutions of antibodies in test tubes or surfaces of glass slides, visible clumping is observed which depends on the size of the antibodies, amount and acidity of the antibody molecule, time of incubation and as well as the environment of the reaction which includes optimum pH, protein concentration among others.
Answer:
B. It showed that microorganisms bring about chemical changes
Explanation:
In 1857 Pasteur was working to solve a problem with the distillers of Lille in wich in their barrels the alcoholic fermentation become in a lactic fermentation, and of course, that was something that they didn't want. Throughout diferents studyes Pasteur discover that different microorganism where involved directly (where responsible) in different types of fermentation. That was the key to start the microbiology studies worldwide.
